IMPROVEMENT IN WIND-WH EELS.

Specification forming part of Letters Patent No. 114,564, dated October 4, 1864.,

To all uhom it may concern Be it known that I, NEHEMIAH TRULL, of Shaker Village, in the county of Merrimack and State of New Hampshire, have invented a new and Improved Wind-Wheel; and I do hereby declare that the following is a full, clear, and exact description thereof,`which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a front view of my invention; Fig. 2, a side sectional view of the same, taken in the line w x, Fig. l; Fig. 3, a detached end view of the lever, with catch whereby the wheel is held in such a position as to be inoperative.

Similar letters of reference indicate like parts.

This invention relates to a new and improved wind-wheel of that class which is designed to be self-regulating; and it consists in a novel and improved manner of applying a governor to the wings or fans of the wheel, whereby said wings or fans, by a very simple means, are made to adjust themselves more or less obliquely to the wind, according to the velocity ofthe latter, and a uniform speed of the wheel obtained under dilferentdegrees of velocity of the wind.

A represents aframing, which may be constructed in any proper manner to support the working parts of the device. On the top of this framing there is an annular cap, B, the latter being permanently attached to the former, and on the cap B there is fitted an annular turn-table, U, which is held in position by vertical rods D,attached to the cap B,and having their upper ends bent over in a horizontal position to tit in a groove, a, in the exterior of the turntable C, the latter being allowed to turn freely on the cap B.

E is thc wind-wheel shaft, the bearings b of which are attached to the turn-table C. This shaft E is tubular and it has a bevelwheel,F,upou it, which gears into a corresponding wheel, Gr, on the upper end of a tubular vertical shaft, H, the lower end of which is stepped in the base of the framing A, as shown at c in Fig. 2.

The wind-wheel is composed of a series of wings or fans, I, each of which has a rod, J, attached longitudinally and centrally to it.

These rods J are fitted in bearings d at the outer or face side of a hub, K, which is secured on the end of the shaft E, (see Fig. 1,) and the inner end of each rod J has a pinion, e, on it, said pinions gearing into racks j' on a shaft, l, which is fitted within the shaft E an'l allowed to slide freely therein.

On the shaft E there is placed a sliding sleeve or collar, M, which is connected with the shaft L by means of pins y g, which pass through said shaft at each end of the sleeve or collar M, the pins g g passing through oblong slots h h in the shaft to admit of the sleeve or collar moving shaft L.

N isa bentlever, the fulcruin pin i of which is in a bracket, O, attached to the inner side of the turn-table G. The upper end of this lever N is a forked prong extending up in a slot or groove at each side of the sleeve or collar M, the lower end being also forked and fitting on a rod,P,between buttons j at the top thereof, the rod P being within the shaft H, and allowed to slide freely up and down therein. The lower part of the rod P is connected by a pin, 7c, with a slide, Q, which is fitted on the shaft H, the pin lo passing through slots Z in shaft H, and the slide Q being connected by arms m m with the rods a a of an ordinary ball-governor, R, as 'shown clearly in Fig. 2. The turntable G has a vane, S, attached to it, which keeps the wind-wheel facing the wind.

On the shaft H, below the slide Q, there is placed a sliding tube, T, to the lower part of which theinner end of a lever, U, is attached.

This lever U has its fulcrum pin o in a short upright, p, on tlrc base of the framing` A, the outer end of said lever passing through a slot, q, in a standard, fr, of the framing. K

From the above description it will be seen that as the wind-wheel rotates by the action of the wind against the wings or fans l, the latter are kept properly presented to the wind by the ball-governor lt. It' the wind be vio lent so as to have a tendency to rotate the wheel rapidly, the governor will actuate the sleeve or collar M, so as to present the wings or fans quite obliquely to the wind,the former assuming a less oblique position when the force of the wind subsides. The shaft L, it will be understood, as it is moved by the governor, turns the rod J through the medium of the pinions c and racks f.

The wind-wheel may be rendered inoperative at any time by raising,` the tube T through the medium of the lever U, the rod I3 hein thereby raised7 and the sleeve or collar M thrown beek so as to cause the wings or fans to be presented edgewise to the wind, the lever being; held in the position to keep the wheel inoperative by a eateh V. (See Fig. 3.)

I do not claim, broadly, the application of a ball-governor to a- Wind-Wheel in order te render the same seltregulating, for that has been previously done; but,

Havin g thus described my invention, I claim as new and desireto 'secure by Letters Patent* 1. The combination of the ball-governor R with the wings or fans I through the medium of the sliding shaft L, fitted Within the wind Wheel shaft E and connected with the rods J of the wings or fans, by means of the pinions e and raelrs f, substantially as set forth.

2. rIhe lever U and sliding` tube' T, when arranged in connection with the governor It, substantially as and for the purpose specified.

NEHEMIAH TRULL.
